Name: Salix lucida ssp. caudata / Rosa woodsii Shrubland Reference: Western Ecology Working Group of... Description: This association occurs in a variety of landscapes and hydrologic regimes across the range of the association. It is known from the northern Great Basin of Nevada, into southeastern Oregon, across the Snake River Plain of southern Idaho, and into Montana. Stands occur from low-elevation (1128 m [3700 feet]), wide floodplains in foothill canyons of high order streams, to low order, moderate-gradient (5% or more), perennial and intermittent streams in relatively narrow V-shaped foothill valleys at mid-elevations (1402-2438 m [4600-8000 feet]). Stands are also known from headwater spring and seep-fed channels. The association typically occurs on stable sites, such as low to moderately high stream terraces (sometimes over 1 m above water table) with silty, sandy, or clayey soils derived from alluvium. Typically found as late-seral, dense, and nearly impenetrable thickets, stands of this association are characterized by mature Salix lucida ssp. caudata about 7 to 8 m tall (with 60 to 90% cover), over an understory of 20 to 50% cover of Rosa woodsii (often most dense in canopy gaps). Ribes aureum, Salix lutea, and Prunus virginiana are commonly associated but with lesser cover than the diagnostic shrubs. While herb species diversity can be moderate, the dense shrub cover prevents light from reaching the soil surface resulting in relatively low cover in the herbaceous layer. Galium triflorum, Maianthemum stellatum, Solidago spp., and Urtica dioica are the most frequently associated forbs, while common graminoids include Carex nebrascensis and Poa pratensis, mostly in moister microsites. This association is probably a late-seral association that forms when floodplain terraces supporting other Salix lucida ssp. caudata associations become drier after natural or disturbance-induced stream channel incision. Because Rosa woodsii often occurs on higher and drier terraces, especially where livestock grazing occurs, it can invade the understory of Salix lucida ssp. caudata stands forming this association.  Accession Code: VB.CC.18498.SALIXLUCIDASSPC Plot-observations of this Community Concept: 0
